* Revamped the trace system. All TraceFormat files are now in the api module. This fixes some problems with not being able to use types of traces
* applied spotless
|
|
* Updated all package versions including kotlin. Updated all web-server tests to run.
* Changed the java version of the tests. OpenDC now only supports java 19.
* small update
* test update
* new update
* updated docker version to 19
* updated docker version to 19

This change updates the build configuration to use Spotless for code
formating of both Kotlin and Java.
|
|
This change updates the repository to remove the use of wildcard imports
everywhere. Wildcard imports are not allowed by default by Ktlint as
well as Google's Java style guide.
|
|
This change adds a re-usable test suite for the interface of the OpenDC
trace API, so implementors can verify whether they match the
specification of the interfaces.
|
|
This change updates the trace API by introducing a limited type system
for the table columns. Previously, the table columns could have any
possible type representable by the JVM. With this change, we limit the
available types to a small type system.
|
|
This change adds support for projecting certain columns of a table. This
enables faster reading for tables with high number of columns.
Currently, we support projection in the Parquet-based workload formats.
Other formats are text-based and will probably not benefit much from
projection.
|
|
This change moves the trace conventions (such as table and column names)
in a separate conv package, so that it is separated from the main API.
This also allows for a potential move into a separate module in the
future.

Tasks from a .gwf trace file did not have dependencies because this
property was not assigned after being read in the GwfTaskTableReader.
I removed the conversion from String to Long in parseParents because it
seems like other readers (the Parquet reader in particular) return
Strings as well, which is why they are converted to Long in line 75 of
TraceHelpers.kt.

This change simplifies the TraceFormat SPI interface by reducing the
number of interfaces that implementors need to implement to only
TraceFormat.
|
|
This change adds support for reading WfCommons workflow traces in
OpenDC. This functionality is available in the new
`opendc-trace-wfformat` module.
|
|
This change starts the process of moving the different trace formats into
separate modules. This change in particular moves the GWF trace format
into a new module, opendc-trace-gwf.
Furthermore, this change also implements the trace API for the GWF
module.
